The bytecodes compiler was not using the new toplevel compiler which has
been extended to compile files. The changes w.r.t to form compilation are
not trivial and involve among other things: externalizing constants,
replacing complex constants with MAKE-LOAD-FORM expressions, interpretation
of EVAL-WHEN statements, fixes in DEFMACRO to expand using EVAL-WHEN...

I have been working on this during the last days. The CVS tree now contains
a different version of the bytecodes compiler that is now capable of
producing files and seems to work with Slime. The only thing is that slime
has to be changed to work with the bytecodes compiler. The patches are
attached.

Nevertheless, consider this all to be experimental. This is a new tool and,
as usual, it will need some fine tuning and polishing.
